LexisNexis sent out notification letters of two separate incidents. A law enforcement customer noticed that an account was used in an unauthorized way. Searches that revealed names, Social Security numbers and driver's license numbers may have been performed by an unauthorized user or without proper reason. The second incident involves a government agency employee who may have used his account in an unauthorized manner to view names, Social Security numbers, addresses and driver's license numbers. Over 220 New York residents were affected by the breaches, but the total number of affected customers nationwide was not revealed.
